I IMPROVEMENT IN SPRINGS FOR RAILWAY-CAR TRUCKS.

Specification forming part of Letters Patent No. 109,358, dated November15, 1870.

To all whom it may concern:

Be it known that I, WILLIAM M. TAYLOR, of Newburg,in the county ofOuyahoga, and in the State of Ohio,h aveinvented certain new and usefulImprovements in Trucks and Springs for Railroad-Oars; and do herebydeclare that the following is a full, clear. and exact descriptionthereof, reference being had to the accompanying drawing, and to theletters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in the construction of springs andspring-seats for railroadcar trucks, as will he hereinafter fullysetforth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a side elevation of arailroad-car truck with my spring andspring-seats attached. Fig. 2 is an enlarged side view of the spring andseat. Fig. 3 is a plan view of the seat, and Fig. 4 is a side view ofanother form of spring involving the same principle.

A represents a railroad-ear truck. of any desired construction, theupper frame, B, thereof resting upon springs O C. These springs are madeof one continuous steel band, coiled by suitable machinery, either inround or oval form, and placed in a seat, D, on the truck.

In making the spring 0 it will be necessary to leave a space between thecoils for oil or other suitable fluid used in tempering it, and afterthe spring is finished a steel plate, a, is

'" inserted in this space, as seen in Fig.2, which plate strengthens thespring.

The seat D is concave, to correspond with the curve of the spring, andhas a flange, b,

on each side, projecting upward for a short distance. In the center, onthe inner side of each flange b, is a vertical pin or projection, e,which fits in notches in the edge of the spring, to hold it in positionand preventitfrom moving.

On the under side of the frame B are other seats, E, fitting on top ofthe spring.

In Fig. 4, I have represented a series of leaves or plates, (1 cl, whichare placed under the spring, to form a support or bearing for the springto strengthen the same. The spring in this case is cut entirely open atthe point of contact, and a block, G, having a flange, i, is laid overthis part of the spring and secured to the flanges of the seat, theflange t' coming in between and separating the ends of the spring wherecut.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. The coil-spring 0, madeeither round or oval, and having a strengthening-plate, (t, insertedbetween its coils, substantially as herein set forth.

2. The concave seat D, provided with flanges b b and projections e a,substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this11th day of March, 1870.
